What does the effect of beta decay on the composition of a nucleus?
Beta decay can change the composition of a nucleus by transforming a neutron into a proton, resulting in the emission of a beta particle (electron) and an antineutrino. This process increases the atomic number of the nucleus while keeping the mass number constant, resulting in a different element.
What is a positively charged particle of the nucleus?
A positively charged particle in the nucleus is a proton. Protons have a positive electrical charge and are responsible for determining the atomic number of an atom.
What element is formed when Ra emits an alpha particle?
When radium (Ra) emits an alpha particle, it transforms into radon (Rn). This process is also known as alpha decay, where an alpha particle is released from the nucleus of the radium atom, resulting in the formation of a new element.
When a radioactive isotope emits a its atomic number increases?
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
Compare and contrast two types of radioactive decay?
Alpha decay involves the emission of an alpha particle (two protons and two neutrons) from the nucleus, resulting in a decrease in atomic number by 2 and mass number by 4. In beta decay, a neutron is transformed into a proton and an electron (beta particle) is emitted from the nucleus, resulting in an increase in atomic number by 1 while the mass number remains the same.
When thorium emits beta particle the resulting nucleus has a atomic number?
The resulting element is protactinium, atomic number 91.
When thorium decays by emmitting an alpha particle what is the atomic number of the resulting nucleus?
88Ra, Radium
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
What happens to the atomic number when the nucleus releases a beta particle?
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
What particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?
No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.
If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?
Two less, since the alpha particle takes away two protons.
What does An alpha particle has the same mass and atomic number as?
Helium nucleus
That particle that gives an element its atomic number is in this part?
The atomic number is determined by the number of protons, which are located in the nucleus.
When a beta particle is ejected from a nucleus the nucleus then has a greater what?
When a beta particle is ejected from a nucleus, the nucleus then has a greater atomic number. This occurs because a neutron in the nucleus is converted into a proton during the beta decay process, resulting in an increase in the number of protons. Consequently, the element changes to the next higher element on the periodic table while the mass number remains unchanged.
